Input-Parallel Output-Series high step-up DC/DC Converter with Coupled Inductor and Switched Capacitor

In this study, the authors propose a non-isolated high step-up interleaved DC/DC converter that can be applied to sustainable energy system. The proposed achieves voltage gain by applying coupled inductor and switched capacitor method based on an boost converter. two inductors connected in parallel with input side have distinct structure. Specifically, single has primary secondary series output circuit. circuit increases being charged discharged through inductor, leakage of regenerated passive clamp performance. Moreover, it is possible select devices low stress on-state resistance switches, thereby reducing loss size, alleviating reverse recovery problem diodes. steady-state analysis operation principle explained was verified prototype 20V voltage, 400V 320W level power.
